GeoSim Review

The Geo Sim Card arrived 24 hours after we ordered it.
It arrived with a detailed set of instructions and a white sim card with all the details needed, we had bought £15 of airtime when we ordered the card so we didn’t' need to top up.
It was easy to follow the instructions and within a minute we had the card installed on the phone.
I entered a UK mobile number +447..... and dialled I got the message please wait, and the call was terminated. A split second later I got a call saying please wait while we connect you.
The call was transferred as a private call to the other mobile and worked immediately with crystal sharp quality and no delays.
I got a status text message afterwards informing me of the call charges for the call.
Text Message I entered a Test Message and sent it to my other phone and within seconds I got the text message originating from my Geo Sim Number I replied to the text message and it arrived instantly on my Geo Sim Phone. We tested the account management online and it worked you can see your balance and last call, we also tried the conference system they have an the call recording, the conference calls was a little tricky to set up and it did require us to try a few times before getting it right, We recommend practicing the conference feature before you have the all important client conference call.
You have to have an unlocked phone to use the GEOSIM - GlobalSimCard
Customer Service:
They both reply to emails and also using the number 154 from your sim card, to check you balance dial 187
We emailed customer support after 6pm UK time as that’s when we arrived at our destination. We also tried calling 154 but there was no reply. However they replied via email in minutes and answered all our questions in a friendly and explanatory matter.
The telephone customer service seem to operate at UK Business Hours.
